Thanks for proving my point. You have moved from actual laboratory demonstration to just-so stories.
Typical brain-dead creationist response. Try looking at a petri dish. That ability is exactly how they TEST FOR BIOLIOGICAL ACTIVITY. Chemical attack is the mode of action in the single-celled world, the ability to quickly adapt to such an attack is well-documented, and by no means "just-so stories". But then, you wouldn't know about that, would you.
